Or an old Miroku. Looks like a baby Browning Superposed, probably cost you about a grand, more-or-less.
The older Miroku and Miroku/Daly O/U's came on both 20 and 28 gauge frame sizes, so know what you are buying. Good luck finding either one at $1K, even these days. When I have seen the baby frame Miroku 28's for sale, the asking price is usually twice that, or more. Of course, they are usually not selling at that price, either.
I have a 686 Onyx 28 on the 20 frame, and it is too heavy for a 28.
You did not mention barrel length or budget, but I would strongly recommend a Ruger Red Label in 28 ga. These have the trimmest frame you are likely to find anywhere, and look very nice with dark, figured wood contrasting the brushed stainless frame. One of the lightest 28's available, come with 26" or 28" barrels, PG or English grip. There was also a version with an engraved frame. Great little gun, and probably the absolute best value out there.
If you are not too concerned with frame size, take a look at the Browning Feather XS Sporting (discontinued), with 28" or 30" barrels. They kept the weight down by using an aluminum alloy frame on the Feather XS, and they do not seem to have had any problems with these guns in small bores. I have one in .410 and a buddy has one in 28. Extremely nice as bird guns, and some came from the factory with killer wood. The 30" barrel option separates this gun from most of the other lightweights out there.
The Sig Rizzini from Bean would be a nice choice, but heavier than the Ruger.
